Title (EN) ROTARY ELECTRIC MACHINE WITH SHRINK-FITTED BEARING
(FR) MACHINE ÉLECTRIQUE TOURNANTE À PALIER FRETTÉ
Abstract:
(EN) The invention relates mainly to a rotary electric machine for a motor vehicle. The machine (10) comprises a shaft (13); a rotor (12); a stator (16) comprising a body (25) provided with slots, and a winding (26) inserted into the slots; a first bearing (37) and a second bearing (38) surrounding an assembly formed by the rotor and the stator and each comprising a housing (40, 44) for rotatably mounting the rotor shaft (13). The first bearing comprises a transverse flange (371) and a cylindrical wall (372) of axial orientation derived from an outer periphery of said flange. The second bearing comprises a transverse flange (48) closing the first bearing and at least one rim (63) projecting from the flange and forming a junction area (64) where it joins the first bearing. Furthermore, the stator body has a region (Z1) of shrink-fitting to the cylindrical wall.
(FR) L'invention porte principalement sur une machine électrique tournante pour véhicule automobile. La machine(10) comporte un arbre (13); un rotor (12); un stator (16) comportant un corps (25) doté d'encoches et un bobinage (26)inséré dans les encoches; un premier palier (37) et un deuxième palier (38) entourant un ensemble formé par le rotor et le stator et comportant chacun un logement (40, 44) pour le montage à rotation de l'arbre de rotor (13). Le premier palier comporte un flasque (371) transversal et une paroi cylindrique (372) d'orientation axiale issue d'une périphérie externe dudit flasque. Le deuxième palier comporte un flasque (48) transversal fermant le premier palier et au moins un rebord (63) s'étendant en saillie à partir du flasque et formant une zone de jonction (64) avec le premier palier. En outre, le corps de stator comporte une zone de frettage (Z1) avec la paroi cylindrique.
